I just knew our two attempts had been successful and the agonising wait between my fertile time and when my period was due was full of expectation. I spotted a little on days 23, 24, 25 and 28, which raised my hopes as I never spotted normally so I started wondering if it was implantation spotting. I did a pregnancy test on day 26, which was positive but I told my husband before I did it that it would be positive. I just felt totally different.
Finding out so very early was initially great but now I'm 6 weeks, 3 days pregnant and it feels like I've been preggers for ages, but all the medical folks keep saying "of course you're still so very early"! From speaking to other women (I work in HR so in a privileged position!) few know they are pregnant like I did. Everyone's different!
